16.6 Communication processor CP 1616 onboard
CP 1616 onboard as IO device
The following diagram shows a typical application: Two PCs each with a CP as a PROFINET
IO device on the IO device layer.
A PC with a CP as PROFINET IO controller, a SIMATIC S7-400 with a CP 443-1 as
PROFINET IO controller and two SIMATIC S7 ET 200S PROFINET IO devices are also
connected in the network.
The IO base device user program runs on the IO device PC. This program accesses the
functions of the IO base user program interface. Data traffic is routed via the CP 1616
onboard communication processor to a PC as PROFINET IO controller or an S7-400
automation system with CP 443-1 over Industrial Ethernet.
